Paten edAPr- 9 Application filed March 19, 19:14. SeriahNo. 825,777.

To all whom it may concern:

Be it known that I, Roen rrr S. KINNEAR, a citizen of the United States,residing I at Laramie, in thecounty of AlbanyandState of lVyoming, haveinvented certain new and useful Improvements in Automatic Car,- JournalCoolers, of which the following is a specification.

This invention relates to improvements in car-axle or journal bQXes.

The invention has for its object, more particularly, to guard againstthe over-heating of the journal or axle, and the consequent hot-box. V

A further object is to provide for carrying out the aforesaid endautomatically and in an effective manner and with facility.

The invention therefore consists of means for delivering a cooling agentto the axle or journal and of subsidiary instrumentality substantiallyas hereinafter more fully disclosed and defined by appended claims.

In the accompanying. drawings is illustrated the preferred embodiment ofmy invention, wherein it will be understood that various changes andmodifications as to the detailed construction and arrangement of partsmay be made without departing from the spirit of the invention, and inwhich drawings Figure 1 is a side elevation of my invention. Fig. 2 is aview partly in longitudinal section and partly in elevation of thesame.Fig. 3 is a partial longitudinal section thereof, parts being brokenaway. Fig. 4: is ,a transverse section of the device, the line ofsection being intermediate the manually actuated valve in the water orcooling agent pipe and the branches of said pipe. Fig. 5 is a fragmentalsectional view of'the same.

In carrying out my invention, I provide in connection with a journalaxle box 1, having a suitable housing'orcasing 2 secured to the outerend thereof, a water-containing receptacle 3 having a plug equippedopening 4 through which it may be supplied with water. Said'receptacle 3has suitably secured thereto and fitted therein, a compartment-chamber 5with a wire screen member 6 facing the interior of the receptacle intothe closed end or wall of which receptacle about centrally thereof,screwed a nozzle or short tubular member 7 The latter has its receivingend beveled the same flaring outwardly and forming a valveis secured orseat 7 which hasfittedthereina correspond:

inglybeveled valve 8 adapted topbe held in member or ,spring. 9effecting connection there-between and the screen 6; The valve 8 hasitsstem 8 guided by means of spiderlikemembers 10 attachedv thereto andmovable within the tubular member or nozzle .7. A-still furtherreceptacle or chamber 11 has screw-threaded connection with the water-.

containing receptacle 3 and may abut the inner end-wall of the chamber5, or be sepauns ated or ope position by a resilient rated or spacedtherefrom in which latter vided end-wall of the compartment-chamber I 5,said pipe 12 being in .alinement with and receiving water from thenozzle 7, its intake. end also serving asa stop for the innerspider-like guide 10 of the stem 8' of the valve 8, as seenparticularlyjin Fig. 5, when the chambers 5 and 11 are in abutment,thus. providing for the holding of the valve open or unseated for thepurpose aforesaid. The receptacle or chamber 11 has threaded orotherwise connected thereto, at one end a. preferably outwardly flaredor enlarged chamber 13 to and within the end of which member 13 isscrew-threaded or otherwise connected a friction-plate 14, the samehaving frictional contact with a friction-plate terminal 15. of the axleor journal 16 suitably borne in the usual way the box 1, which frictionplates will be further referred to later.

'Tshe waterrpipe 12 :is provided with a valve '17 having a hand disk orwheel equipped stem 18 for its convenient manual manipulation inproviding for controlling the passage or delivery of the watertherethrough. The pipe 12 is provided beyond the valve 17, with a union19 by means of'which connection is effected therebetween andwater-spraying or discharge pipes 20, the outer ends of said pipes beingdisposed so as to effect the discharge or spraying of the water upon theaxle or journal, as seen particularly in Figs. 2 and 3, thus providingfor cooling or reducing the temperature of sa1d ournal or axle, andaccordingly guarding against a hot box.

A plurality of additional pipes 21 suitably held in place in the innerend-wall of the chamber 12 and in the outer end wall of said chamber, soas to extend parallel with, and close to the water-pipe 12, a certainportion of their lengths are suitably curved or carried upwardly, asshown in Fig. 3, their upper ends being disposed contiguous to thefriction plate 14, and in the upper portion of the chamber 13 to receivethe rising hot-air therein, resulting from the heating action generatedby the frictional contact between the journal carried plate 15 and theplate 14: as is obvious will take place. The hot air entering andpassing into the pipes 21, it is apparent, will heat said pipes and theradiated heat therefrom will cause the heating of the water pipe 12 andaccordingly guard against thefreezing of the water therein during theprevalence of low temperatures.

The structure resulting from the connected chambers 3, 11, and 13 isresiliently supported in position to conform to the incidentalvibrations of the axle or ournal within the housing or casing 2 by meansof out standing studs 22 shown as castings with the chamber 11 andsimilar studs 23 shown as castings with the casing or housing, saidstuds receiving rods 24, suitably held therein, and encompassed byresilient members or springs 25 held between said studs, as clearlydisclosed by Figs. 8 and 2.

I claim l. A device of the type described including an attachment for acar-axle box equipped with a cooling agent containing means,comprisingchambers, one having a reticulated wall, the other chamberhaving a nozzle provided with a spring-controlled valve, with itscontrolling spring connected to said reticulated wall, the third chamberadapted to be spaced from the intermediate chamber for seating saidvalve, and a pipe alining said nozzle and provided with branch pipes ortubes adapted to deliver or s ra the cooling a ent u on the car-axle.

P y g P Y 2. A device of the type described including an attachment fora car-axle box, and a cooling agent containing means comprisingchambers, one chamber being provided with a nozzle having aspring-controlled valve, the third chamber being adjustable with respectto the second or intermediate chamber and adapted to retain said valveunseated when in contact with said intermediate chamber, a delivery pipearranged to receive the cooling agent from said nozzle, and a pluralityof pipes arranged parallel with and contiguous to said delivery pipe,and means adapted by frictional heat-generating action to deliverhot-air into said plurality of pipes during the prevalence of lowtemperature.

- 3. A device of the type described including an attachment for acar-axle or journal box, a cooling agent containing means, a sub-chamberwithin the cooling agent containing means proper having a reticulatedwall in its otherwise open end through which the cooling agent enterssaid subchamber, the opposite wall of said subchamber having avalve-controlled nozzle extending therethrough, a third chamber havingits casing adjustably connected to the casing of said sub-chamber, afourth chamber having its casing connected to the casing of the thirdchamber and provided with a friction end-wall plate, the car-axle havinga friction plate rotating in frictional contact with the aforesaidplate, a delivery pipe receiving the cooling agent from said nozzle,said delivery pipe having a plurality of branches adapted to spray ordischarge the cooling agent upon the car-axle, and an additionalplurality of pipes extending parallel and contiguous to said deliverypipe for a portion of their lengths, the remaining portions of saidpipesextending upwardly into the upper portion of said fourth chamberand receiving the hot-,air therefrom for heating by radiation, saiddelivery pipe during the prevalence of low temperature.

In testimony whereof I aflix mysignature in presence of two witnesses.
